Comment (by ryandesign@…):

 According to your log, the problem is MacPorts cannot resolve any hosts:

 {{{
 :debug:archivefetch Fetching archive failed:: Could not resolve host:
 packages.macports.org
 }}}

 Duplicate of #50986. Instead of beginning by installing demeter, which
 tries to install all its hundreds of dependencies in one go, install some
 of the dependencies of demeter first separately. (You can see a list of
 them by running `port deps demeter`)
